[QUESTION] Additional attachments in PDF #153

Open wurst-hans opened 3 hours ago

wurst-hans commented 3 hours ago

I would like to thank you very much for your library, it is a really big help (I'm a German user). I have not yet been able to find any information here on whether I can also embed attachments such as timesheets (which I usually embed in the XRechnung) directly in ZUGFeRD. Unfortunately, I don't understand anything about PDF/A, but if I understand the ZUGFeRD specification correctly, you seem to be able to attach additional documents with AFRelationship/Supplement. Hence my question: Does your library support adding and reading additional attachments from the PDF?

Many thanks for the kind words

There are currently no plans to include additional attachments in the ZUGFeRD PDF. However, it is certainly a good idea to include this in the future.

Kind regards

Hi @wurst-hans,

An addendum on my part: One idea would be to include the additional documents in the embedded XML. My library offers possibilities for this. The ZugferdDocumentBuilder, for example, provides a method addDocumentAdditionalReferencedDocument for this purpose. You can pass a file name with the file to be embedded to this method.
